The play opens with discussion of Shelby's wedding day to her fiancé, Jackson, in the fictional northwestern Louisianaparish of Chinquapin at Truvy's in-home beauty parlour where the women regularly gather. It covers events over the next three years with Shelby's Type 1 diabetes and how the women interact at times with conflict but in the end resolved friends: Shelby's decision to have a child despite the complication that could result from her condition, Clairee's friendship with the curmudgeon Ouiser; Annelle's transformation from a shy, anxious newcomer in town to a good-time girl then repentant revival-tent Christian; and Truvy's relationships with the men in her family. Although the main storyline involves Shelby, her mother M'Lynn, and Shelby's medical battles, the underlying group-friendship among all six women is prominent throughout the drama

Inspired by the playwright's youthful experience as a staff writer on Sid Caesar's Your Show of Shows, with all the attendant comic drama as the harried writing staff frantically scrambles to top each other with gags while competing for the attention of star madman "Max Prince".
